Like others have said, the Can does work under the right conditions (a buck you can actually see). I have only ever heard a doe make that "bleat" sound on one occasion, but that Can sounds EXACTLY like it! I have brought in 3 bucks during the rut with the Can. In 2010 I had a nice 8pt come running straight towards me so fast that I almost didn't have enough time to put the Can back in my pocket and grab my bow. Honestly.
